From Wikipedia .. Security means protecting data from the database and the destructive forces do not want to act from legitimate users.

To the end of this article covers the basic ways you can lose data, what can you do to prevent and if the worst happens what options you have for restoring it.

Data Security – basicsWhen we talk about data security, it is a subject that covers several broad areas, think about things like hardware / software failures, power surge, theft of data – both locally on the machine or remotely via the internet and the same again for the data is accidentally deleted, it can happen remotely or locally machine.

How you setup your system and indeed the organization or at home can have a major impact on the security of your data. You also have to protect from a way of losing but you are protected from all forms? Read on to get some more information and facts about avoiding data loss security.Loss PreventionEach field can be huge discussion but we will discuss the basics here to get your overall overview.

Hardware FailuresYou will have some kind of experience of hardware / software and computer failures that may or may not result in loss of data, but usually always produce some level of research frustration.

We some time ago to around 600 work when it comes to computer store I worked at. We remember what each machine is a sin, 34% had a hard drive failure; distant second is the failure of the motherboard 17% So the most likely part to fail on a computer hard drive. . There are several types of data backup in place to prevent the loss of valuable data, even if it is just a memory stick for home user.

Other options include:

1. External Hard Drive

The use of regular external hard drive to copy the files you need to back up, it is fine but if travel is permanently attached, you should be more careful in making backup regularly.

2. RAID 1 or 5

There are others but these two popular small-scale systems. It works by using 2 or more hard drives make redundancy in case the hard drive fails. Relatively inexpensive, easy to setup. Also after that runs do not need to think about it.

3. Local Storage Network

There are solutions to a network attached hard drive allows you to back up multiple systems simultaneously on a network location. It can be very cost effective if you have 3 or more systems. Beware, if the storage network consists of a single hard drive, you can lose all your backup in case the drive fails. Again, usually automatically after running

4. Cloud Storage

This means that you save your data to a storage area at some other location, possibly in Sydney or even in the United States. This takes you to the data in data sovereignty issues have to go abroad and subject to the laws of that country. Also the number of times it appears if you select the type of data storage, other entities can through your stuff. Usually once running.

Software Automatic Failure

It was not far behind in terms of hard drive data loss failure. Usually occurs when something unexpected happens that the software can not cope. If it involves your data handling software at that time and then the result may lose data. Here are some typical examples:

1. USB Memory Stick

While the USB stick attached to your system, there is an open ‘handling’ Runs helped facilitate the transfer of data back and forth between the computer and sticks. If you suddenly remove a stick and continuous transfer of data is lost. In bad cases the entire contents of the stick is lost. Always use a secure erase button on the bottom right of the Windows Task bar.

2. Error in File System

It is a common cause of Windows fails to start, it means that the file system (think of the index library) taken and the software can not find what he was looking for. Regular is caused by a virus and electrical interference, where the power is lost while the file system is being updated. Usually it is pretty bad unless you can withdraw from this type of problem, but no data loss uncommon.

Electrical surge

It can be caused by many things and actually occur at any time. The damage depends on the strength of the waves and can be anything from a blown fuse to completely fry your computer using the accompanying smoke (as reported in Darwin a few years ago). In all cases an investment in the right surge protector is important. You’ll want to spend around $ 70 to $ 90 mark for 5-7 protective harbor. Some of the causes power surge below.

1. Lightning

The number one cause of the increase, it can be transmitted long distances through power lines and telephone lines, so if you can hear the thunder of the land can be an idea to unplug your precious electronic possessions.

2. Blew transformers

Your local transformer may fail and send big waves through electrical lines, it may not happen often, but the effect will be great and widespread.

3. Imaginative Power

There are always some electrical work report annually goes wrong that causes damage to household appliances. Make sure you always use a quality electrician.

4. Failed Electronics

Ancient device or a device that can send waves wet etc. through your household wiring and other devices affect attached.
